We have a snow corn that is about 2 years old. He had a RI when we first got him, we think from the stress of moving, a failing heat source etc. Treated him with injections. He was fine. A year later he got what we thought was another one. He started sneezing, took him to the vet, the vet said he looked fine. A week later he was sneezing more and had what looked like brown discharge around the mouth and nose though it could be from rubbing on his cork bark because it was new and he kept exploring it, so we took him to the vet. We gave him antibiotics for two weeks, and he seemed to clear up. Two weeks later, he is sneezing again.

He is in a 75 gallon tank, with a custom top. He has a heat pad and a lamp. The temp in his cage was running about 85-87 on the hot side, and cooled down from there. We increased his temperature to about 95 on the hot side as per vets instructions. He is on aspen bedding because the heat pad says not to use newspaper, and I have been told not to use carpet on corns. Plus he never seems happy unless he can burrow. He has a box with moss in it for a humid hide which he uses sometimes.

Can this sneezing be something else? Could it be the bedding? Is there another type of bedding I can use? I could use carefresh but I work with it every day and its dry and dusty as heck.
